SPECIFICATION forming part of Letters Patent No. 447,584, dated March 3, 1891.

Application filed June 12, 1890- Serial No. 355,218. (No model.)

To all whom it may concern:

Be it known that I, JOHN F. ROWELL, a citizen of the United States. and a resident of Hookset, county of Merrimac, and State of New Hampshire, have invented certain new and useful Improvements in Wash-Boilers, of which the following is a specification.

My invention has for its object to provide a wash-boiler which, while simple and cheap in construction and fulfilling all the requirements of the usual boiler in a superior manner, shall in addition thereto prevent the overflow of water upon the stove or'floor when in use.

To these ends the invention consists, first, in a wash-boiler which is provided on its interior near its top with an inwardly-curved deflector extending entirely around the same, whereby to deflect the water inwardly away from the walls when rising upward along their interior; second, in the combination, with a boiler as thus constructed, of a cover for oo-operating therewith, having a presser secured to its under side for pressing the clothes or other articles down below the top of the deflector and holding them in that position, all as will hereinafter more fully appear.

Referring to the accompanying drawings, which form a part of this specification, Figures 1 and 4 are vertical longitudinal and transverse sections, respectively, of a washboiler constructed in accordance with my invention; Fig. 2, a top or plan view thereof with the cover removed; Fig. 3, a bottom or reverse plan view of the cover detached, and Figs. 5 and 6 sectional details showin slightlymoditied ways of supporting the deflector within the boiler.

In all the figures like letters are employed to designate corresponding parts.

A indicates the body of the boiler, which in practice may be constructed in any of the wellknown forms, the partic ular type, however, selected by me for the exempliflcation of my invention being that in which the front and rear walls are rectilinear and parallel, and the ends joining the same are of semicircular contour. In the construction of this body any of the well-known kinds of material may be employed. I prefer, however, to make it of sheet metal and to provide it with a contracted bottom a, which is adapted to fit the appropriate receptacle in the top of the stove or range, and with suitable handles ct a, secured to the outer surface of its ends near their top,whereby to permit of its easy handling.

Located in the interior of the boiler near its top and extending wholly around the same is the deflector B, by means of which the water passing up the inner Walls of the boiler during ebullition or otherwise is deflected inwardly away from the same and prevented from flowing over their tops upon the stove or floor. In the preferred form of construction this deflector curves inward from its lower to its upper edge, and maybe provided with a series of apertures 11, leading through the same, if desired, to permit of any water thrown upon its upper or outer side flowing downward therethrough. As thus constructed, the deflector maybe fixedly secured to the interior of the body-or made separable and detachable therefrom, as desired. In Figs. 1

and at I have illustrated it as fixedly secured thereto by solder, and this is the construction I prefer to adopt when the boiler is made new throughout; but in Figs. 5and 6 I have shown it as made separable and detachable, whereby to'adapt it for use with old boilers, and such is the construction that will preferably be employed when used in connection therewith. When made separable and detachable, it may be either supported in place by friction between its exterior surface and the interior walls of the boiler, as shown in Fig. 5, or by hooks b secured thereto or formed thereon, engaging with the top of such walls, as shown, for instance, in Fig. 6. I prefer, however, to employ the latter construction when the de flector is made separable and detachable, as a firmer support for the same is afforded thereby.

0 indicates the cover, by means of which the top of the boiler may be closed. This cover is conveniently constructed of the usual dome shape, and is provided with a handle 0 for lifting the same and with a flange 0, depending from its under side and closely fitting the interior of the top of the boiler, whereby to hold the cover in place when adjusted thereon.

Secured to the under side of the cover is the presser D, by means of which the clothes or other articles may be forced down into the boiler below the upper edge of the deflector and there hold. This presser may be constructed in various ways. I prefer, however, to make it of wire which is composed either of a non-oxidizablematerial or one rendered so on its exterior by galvanizing or otherwise, and to dispose it, as shown in the drawings, with one piece dot the wire bent into substantially the form of the upperend of the boiler and secured to the under side of the cover by stands d and the other two pieces (Z (Z thereof underlying the formerlongitudinally and transversely in the form of a cross and secured to the cover by their ends, which are bent upward for that purpose. The presser being thus secured to the under side of the cover, will, when the latter is applied to the boiler, project into the body of the boiler su ffieiently to force the clothes some distance below the upper edge of the deflector, thereby permitting the water deflected inwardly by the deflector not only to pass over the clothes toward the center of the boiler, but also to pass downwardly through them to be heated again, and in order to maintain it in that position and prevent it from being raised by the action of the clothes during ebullition I provide the cover wit-h hooks ffand hinged plate or hasp g, which when the cover is applied to the boiler may be respectively engaged with staples ff and pin g, secured to the latter, and firmly hold the former from all vertical or other movement thereon, suitable apertures c 6 being formed through the cover to permit of the steam generated during the boiling operation passing therethrough. The clothes or other articles contained in the boiler being thus held down below the upper edge of the deflector, and the action of the deflector upon the water serving to deflect it inward toward the center of the boiler, not only prevents it from overflowing upon the stove or floor during ebullition, but

also insures its passage down through the contents of the boiler as it descends to be again heated, the results of which are to increase its detergent effects, and thereby renderthe boiler more efficient in operation. The cover having been locked to the boiler may be removed therefrom when desired by simply nnhasping the hinged plate g from its pin and swinging the cover upward until the flange c is raised above the boiler, when the hooks ff maybe disengaged from the staples and the cover removed.

In the foregoing I have described the best means contemplated by me for carrying my invention into practice; but I wish it distinctly understood that I do not limit myself strictly thereto, as it is obvious that I may modify the same in various ways without departing from the spirit thereof.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. A boiler provided on its interior near its top with an inwardly-curved deflector B, extending entirely around the boiler and provided with numerous apertures b, whereby the ebullient water is arrested from overflowing the sides of the boiler and is turned inwardly and returned to the bottom of the boiler, substantially as described.

2. The combination, with a boiler having an inwardly-curved deflector B arranged near its top and extending entirely around the boiler, of a cover provided with a presser secured to and depending from its under side, and locking devices whereby the cover may be secured to the boiler and prevented from rising by the action of the clothes thereon during ebulli ion, substantially as described.

In testimony whereof I have hereunto set my hand this 7th day of June, 1890.

JOHN F. ROlVELL.
